What is barge-in in voice AI?
Barge-in explained: why letting a caller interrupt the agent matters for a natural conversation.

Why barge-in matters
Real conversations are full of interruptions: a caller answers before the agent finishes, or cuts in with a question. An agent that cannot be interrupted keeps reading its line while the caller is talking. Barge-in, also called interruption handling, is one of the clearest signals of a good voice agent.
How to test barge-in on a call
Call the agent and start talking while it is mid-sentence. A good agent stops within a moment, listens, and answers what you said rather than finishing its line. Then try a short 'haan' or 'okay' while it speaks: it should keep going, because a listener's acknowledgement is not an attempt to take the turn.
Frequently asked questions
Is barge-in the same as turn detection?
They are related. Turn detection decides when a speaker has finished; barge-in is the agent yielding the moment the caller starts, even mid-sentence.
Why does my voice agent stop talking when I say 'okay'?
Its barge-in is too sensitive and treats a short acknowledgement as an interruption. Better agents tell a backchannel such as 'okay' or 'haan' apart from a real attempt to speak, and carry on.
